  Hi,

  About 2 years ago, I bought a 520 ST with a monochrome monitor and 2
  single-density drives.  As it turned out here in school, I am mainly
  using it as a terminal.  (I use Uniterm.)  However, I have a synth
  (a Kawai K1) and a MIDI sequencer (the cheaper of the 2 Dr.T's), and
  would like to use them together.

The problem:

  When the ST receives a note (or, probably, anything) through MIDI IN,
  it pipes it through to MIDI OUT.  My evidence is that when I hook both
  cables between the ST and the synth, the synth reports that it is
  *receiving* info whenever I play a noth on its keyboard.  The sound is
  slightly different, and the number of voices is cut in half (because
  every note is being played twice.  This has nothing to do with the
  Dr.T sequencer, because it happens when I just turn on the ST.

Some possible explainations:

  o  Perhaps this is the proper default state for the MIDI ports, and
     sequencers are expected to perform some kind of initialization to take
     them out of that state.  In this case, it *would* be Dr.T's fault. 

  o  Something with my synth.  I don't understand the technical aspects
     of MIDI perfectly; however....  I had another synth (a Yamaha
     DX100), and whenever I ran Dr.T's with both cables hooked up to it,
     the synth reports a MIDI error and starts acting strangely.  I 
     can't remember ever trying it without running Dr.T's (like I tried
     with the Kawai).  

Question:

  Does anybody know why this is happening?  Does anybody have any
  suggestions for a solution?  Any help would be *greatly* appreciated.
  Thanx.
